DC Power Relay (200A Type) G9EC-1

A DC power relay capable of interrupting high-voltage, high-DC current loads. A low noise design with a long service life and environmental resistance.
[Features]
· The switching section and driving section are gas-injected, hermetically sealed and small, allowing them to interrupt high-capacity loads.
· Requires no arc space, helping ensure safety and more efficient use of space.
· The highly reliable contacts are not affected by the ambient atmosphere.
· Its miniaturization and optimum design ensures no restrictions on the mounting direction.
· UL/CSA standard UL508 approved.
[Applications]
· Can be widely used for FA equipment and non-FA equipment.
